>> no. i don't believe it. i don't know how i'm going to find her. so that's all. >> reporter: cyndy grew up in a connecticut family. she had all but given up finding her birth mother. >> i'd gone to korea last year kind of looking for her, and i made peace with the fact that i'd probably never find her. >> reporter: when a dna sample led her to sun cha. >> it says 99.99% she is your biological mother. i so much wanted it to be true. >> reporter: there was more. her mom had been living on the west coast. they had been in the same country for decades. cyndy flew to tacoma this weekend to meet her mom. >> my daughter cyndy. >> hello. you're so beautiful. >> i always say where can i find her? i don't know where she is. >> we're back together now. >> i know. >> reporter: when we sat with them, they couldn't stop holding each other, as if they were afraid they might lose each other again. what does it say about your mother that she was willing to be open about this secret that all of her life she hadn't shared with her family? >> it's confirmation that she did love me. >> reporter: at sun cha's home there was a family reunion. cyndy with her newly found sisters and brother. >> it's what all of us who are adopted want, is for our existence to be validated. >> here we go. >> and to know that our parents loved us. >> reporter: barry petersen, cbs news, tacoma, washington. >> that's the "overnight news" for this wednesday. for some of you the news continues. for others check back with us a little later for the morning news and "cbs this morning." from the broadcast center in new york city i'm scott pelley. >> announcer: this is the "cbs overnight news." welcome to the "overnight news." i'm don dahler. mosquito season is right around the corner, but the battle against the zika virus continues to be fought in washington. after a three-month delay the senate cleared the way to fund the fight. but it falls far short of the president's request for nearly $2 billion. zika can cause birth defects and is mostly transmitted by mosquitos. david begnaud is in coral springs, florida, which has its fair share of mosquitos. >> reporter: mosquito controllers insist the zika threat is at florida's doorstep. a few infected mosquitos can cause a large outbreak. here in broward county in south florida where we are they're getting 500 calls a day requesting mosquito spraying. that's ten times the amount they're used to. >> when it rains it fills up. mosquitos grow and four or five days from now adults will be flying around. >> reporter: on the u.s. mainland florida is the front line in the zika fight. more than 100 cases have been reported here. more than any other state. you're not going to get zika in the woods while you're hunting or at the lake when you're on your boat. you might get it at your front door. >> that's exactly right. while you're standing next to your car to go on your hunting trip or to the beach or to the park, that's when the mosquitos will fly up and bite you in the ankle. it's not in those typical place that's we as floridians think of as mosquito biting territory. >> reporter: michael doyle of the florida keys mosquito district suspects zika cases will rise as summer approaches. as of now all of florida's zika patients contracted the virus from travel-related exposure. in february the white house requested approximately $1.9 billion in emergency funding. congress is debating it. >> we need to deal with this seriously. >> reporter: republican senator marco rubio represents florida. >> we're going to spend a lot more money if we don't deal with this on the front end. if this become a serious outbreak it's not going to cost 1.9 billion. it could cost 4 billion or 5 billion. >> reporter: republican hal rogers, chairman of the appropriations committee, is a critic. >> the request they sent us would allow the $1.9 billion to be used for anything in the government. it's almost like a slush fund. >> mosquitos don't know whether their target is a democrat or a republican. the zika impacts all of us. >> reporter: democratic congresswoman debio wasserman schultz, also from florida, insists part of the money will be used to develop a zika vaccine and raise awareness in a state that thrives on tourism. >> we're now going into the mosquito season. every week the chances of having enough of them to start trans t transmitting it from travelers to local people increases. >> reinforcements are being sent to chicago's o'hare airport, where hundreds of air travelers missed their flights over the past few days because they couldn't get through security. o'hare is getting 50 more security officers and four more bomb-sniffing dogs. but the trouble at the security checkpoints is not limited to chicago. kris van cleave reports from los angeles international. >> this airport is telling flyers to be in these lines two and three hours early as the number of passengers are going to go up as the summer travel season gets going. already one airline tells "cbs this morning" l.a.x. makes its top five for missed flights because of tsa lines and now flyers from coast to coast are striking back on social media. security lines that seem to never end are becoming the new normal in chicago. at o'hare international airport we're talking about wait times up to three hours. long enough to strand more than 100 passengers overnight sunday, forcing many to sleep on cots. >> what's the problem? why is this happening? >> this is absurd. >> they need to hire more people. >> reporter: american airlines says 450 customers missed their flights at o'hare sunday alone because of the long lines. this headline dubbed the trip through security a slow march through hell. the tsa blames the issue at o'hare on increased passenger volume, but it's not just chicago. flyers around the country are blasting the tsa on social media using the hashtag ihatethewait to post pictures of long lines. at least 6,400 american airlines passengers missed their flights at the nation's top 20 airports. and that's in just the last week. >> we are trying to work with the tsa. this is an effort to help flag to the tsa where the massive wait times are. >> reporter: melanie hinton with airlines for america, a trade association representing several major air carriers, created that hashtag. >> let your fellow passengers know if you have an excessive wait time. >> reporter: earlier this month the three new york-area airports joined seattle and atlanta in threatening to drop the tsa for private screeners. >> there will be wait times. >> reporter: friday secretary of homeland security jeh johnson said the tsa is looking to hire hundreds more screeners and will authorize overtime for tens of thousands of officers. but that may not be enough. as the peak summer travel rush arrives. >> three hours is not ideal. we want to reduce that as much as possible without compromising the safety of the american public. >> reporter: so how did we get here? well, congress capped the number of tsa screeners, thinking there would be millions of more flyers enrolled in precheck which is expedited screening. enrollment has lagged. you have seen the tsa experience very high turnover, and they've struggled to maintain their staffing numbers. this as the number of flyers has steadily increased. on average, one person is killed each day during a high-speed police chase somewhere in america. but a new device could soon make those chases a thing of the past. dean reynolds reports. >> high speeds, wet roads. >> reporter: adrenaline-pumping cops and robbers pursuits are something of a tv addiction. police departments across the country are looking for a safer way to nab suspects on the run. >> he played a game of mercedes pinball. >> i'm going to take my loading tool. >> interpreter: a>> reporter: ad now more than 50 agencies are using a system invented by a company called star chase whose president is trevor fishbach. >> we've had zero fatalities, zero injuries, zero property damage and zero liability. >> reporter: this is how it works. compressed air units are installed in the grill of police cruisers, containing two 4 1/2-inch projectiles packed with gps satellite trackers and coated with enough adhesive to make them stick to a fleeing vehicle. when a suspect runs from a traffic stop, an officer can fire the projectiles at the suspect's car and basically relax. no need for sirens or lights or 90-mile-an-hour chases that could kill people. computers read the gps signal and track the vehicle in question. a trial of the star chase system has been under way in milwaukee since december. >> i've actually had a lot of success with it. >> reporter: officer kim lastrila controls the projectiles from a button on her dashboard or a fob in her hand. >> at this point he's starting to make a break for it. >> yep. >> and you do that. >> reporter: right now the projectiles stick about 50% of the time, though with training milwaukee expects that number to be about 75%. and they do have some trouble in wet conditions. but there's no question that the technology reduces stress for the police and the suspects. >> the longer they go unpursued the more their driving behavior settles down because they don't want to get killed either. >> reporter: but they do get arrested. of 28 successful uses of starchase in its trial period, 17 people were taken into custody, and 26 stolen cars were recovered. each unit costs about five grand. that's a lot of money. but when you consider that the number one cause of death for police officers in this country involves car crashes, ♪ we're going to prove just how wet and sticky your current gel antiperspirant is. ♪ and now we're going to show you how degree dry spray is different. degree dry spray. goes on instantly dry for a cleaner feel. degree. it won't let you down. hey spray 'n wash is back...ws?

>> it's paradoxical for an architect. the only thing you can see is all the compromises, all the battles, the [ bleep ] that couldn't be fixed. >> reporter: the rise and rise of young mr. ingalls started here in copenhagen where he grew up. his father an engineer. his mother a dentist. >> i wanted to be a cartoonist but there was no cartoon academy. so i enrolled in the danish academy of architecture and i got schmitt nguyen architecture. >> reporter: from the beginning ingels said he set out to disrupt the architecture's tyranny of boring blocks. >> i said can you tell me why modern buggs are so boring? because people had this idea that in the good old days architecture had like ornament and towers and spires and gargoyles and today it just becomes very practical. >> reporter: after graduation in ingels lasted just two years working for famed architect rem kulhaus before setting off on his own. in 2005 he formed big, for the bjarke ingels group from his tiny apartment in copenhagen. denmark is one of the smallest countries on the planet and there was something funny about calling a company big. i think if i would have started big in america i would have probably never called it big. there was nothing but like a little bit of local small country humor in the idea. >> reporter: almost immediately he began to win design competitions, making a name for himself with inventive whimsical designs for what could often be deadly boring. suburban apartment buildings. >> five years ago we had built a few projects in copenhagen that were in a way ordinary projects like housing and parking and shops and offices but we had put them together in a way that created maybe remarkable results. and suddenly we got an invitation to come to new york and look at the site on 57th street. and in a way i had nothing better to do, so i thought why don't i move to new york and see how it goes? >> reporter: it went pretty well. he now oversees 300 employees between offices in new york and coalen haigen. >> the more it looks like -- >> reporter: ingels believes his success comes from his ability to combine the practical with the fantastical. like this harbor bath in copenhagen where swimmers can swim in the city's harbor. or how about this? the design for the just unveiled new redskins stadium, complete with a moat for all those kayaking tailgaters. >> tailgating literally becomes a picnic in the park. >> reporter: the culture at big is intense. but in off hours blowing off steam dressed as their favorite comic book hero isn't uncommon. that's the boss, armed with a gun full of tequila. >> the way we work is maybe unlike certain architects that have a very particular style where it is the auteur, it has to be the design principal who makes the strokes of genius. i don't have to come up with the best idea. it is my job to make sure that it is always the best idea that wins. >> i think he's really a wonderful spokesman for himself. and for -- i would say also for the possibility that architecture can really make life better for people. >> michael kimmelman is the architecture critic for the "new york times." he says ingels has combined natural talent with a mastery of marketing, a so-called starchitect. >> it's rare you get architects who are really in their 30s and 40s who get to build big projects. and bjarke's figured that out partly by selling a certain youthful notion of the old starchitect model, which is glamour and spectacle. and he does something that i think is very important nowadays, which is to combine a notion of his own work with and larger social purpose. >> reporter: the thing that strikes me is a hot of people are willing to lay down billions of dollars. >> billions, with a b, yeah. >> reporter: on this kid. >> it's true. it is a gamble. he's got a lot of work coming down the pike. how is he going to make sure that work is not recycled, it's original, that it's finished well? >> there must be criticism by other architects. >> the more you are up to something interesting, the more it's going to inspire prize and criticism. >> reporter: and in your case? >> we have a fair amount of sunshine and the opposite. and i think if you would take all of that to heart you wouldn't be able to, you know, draw a line or lay a brick. >> reporter: ingels has become a celebrity at home in denmark where he's designing the new headquarters of the most iconic of toymakers, lego. at the topping off ceremony in october townspeople waited in line in the rain to catch a glimpse of the new building it its architect. >> that's the tieback. >> reporter: that fame has also allowed him to take more risks, to add more spectacle to his creations. this is a chimney that belches steam rings. it will go atop a green garbage incinerating power plant in copenhagen. the roof doubles as a ski slope. >> the building says come and look at me. >> since this power plant is really saving a lot of co2 emissions it's almost a complete reversal of the symbolism of chimneys. >> reporter: the idea for the outrageous structure originally started as a joke. >> normally you would want to be as far away from a power plant as possible because it's polluting, it's noisy, it's smelly. but this is so clean that you essentially have clean mountain air on the roof of it and we thought, maybe it would make sense to make it a ski slope. so yeah, great idea, like let's get serious. when you stop laughing it felt like wait a minute, maybe this is not so stupid, maybe it's actually a good idea. >> reporter: never mind the starchitect appelation. you're a activist. >> if you're just reaffirming the status quo, then you are mission the point that the city is never complete. so every project we do somehow has to count. >> reorter: particularly this one. the design for two world trade center, the final tower set to rise on the site. >> 2 world trade center is roughly going to be as tall as 1 world trade but without the spire. and if you see it from here it would appear as a series of seven city blocks of different proportions stepping up toward the sky. >> you can see the full report along with many other morley breyers peanut butter gelato, rich chocolate sauce. peanut butter cups. tonight is perfect. can someone read me another story?

wow. >> reporter: the school founder, shafiq suleman, told us he offers free tuition to encourage parents to send their children back to class but sometimes that's not enough. >> parents aren't earning enough money to feed their families. >> no. so they have to -- they're being forced to send their kids to work. >> reporter: out of desperation. >> yes. yes. they've got no choice. they have to send their children. >> reporter: layla aqja is a psychologist who treats syrian child refugees and their families and told us many factories prefer to hire children over their parents. >> you can overwork the children and they're not going to be oppositional. they're not going to ask for their rights. they don't know their rights. so they're just going to work like slaves. and it's easier to keep them as slaves than doing it to an adult. >> reporter: turkey has taken in around 3 million syrian refugees, spending billions of dollars to shelter and feed them. but while they're safe here, there's very little stable work and not much hope of building a future. that's why so many syrians have risked their lives in rickety boats, to reach europe. but now the european union has promised turkey nearly $7 billion in return for its help stopping the refugees. and the crackdown has worked. for syrians the door to europe has slammed shut. but the factories that prey on them appear to be operating with ipunity. and hundreds of thousands of syrian children in turkey are growing up illiterate and powerless to change their fate., most of the world's rhinos can be found on game reserves in south africa. but that doesn't mean they're safe. poachers still manage to get in, kill the animals, and take their horns. apparently, they're big business in asia. debora patta is at one game reserve taking an unusual step to protect the rhinos. >> reporter: this rhino is one of dozens at the phinda game reserve that has been sedated. so that their horns can be removed. ranger simon naylor knows his unmarked rhinos, their horns a deadly bounty on their heads. he has made an uneasy peace with the difficult decision to dehorn the rhino population. which some critics say may harm the rhino's ability to live successfully in the wild. >> i think in the last few years we've reached a tipping point in africa and certainly in south africa. there are more deaths now than births. so it's a species that's heading toward extinction if we don't do something drastic. >> reporter: naylor directs veterinarian mike toft on which rhino to dart with a potent tranquilizer. toft must ensure the precise dosage when he fires from the helicopter. too much could be lethal. the rhino is quickly blindfolded. it's hard to watch. but the rhino is not in any pain. although the process is briefly traumatic, toft says it's a bit like filing a human nail. >> i'd rather see this little guy upright in two years' time than in a ditch upside down and bloated dead from having his horn poached. for me it's a no-brainer. >> reporter: this rhino horn is what this war is being fought over. it is so valuable to poachers that it is immediately whisked off the property and taken to a secret location out of the reach of criminal syndicates. the appetite for rhino horn powder is so high that organized crime rings can net around $150,000 for an average horn. the trade is driven primarily by vietnam. where it's sold under the delusional belief it cures cancer and enhanses virtual. for this at least three rhino are killed every day in south africa, and toft is on the front lines. the dehorned rhino is sprayed with a purple disinfectant. the mark of survival. and then injected with an antidote to counteract the grogginess. >> 100%. he's nice and relaxed. >> reporter: there is no permanent damage. it will become increasingly rare to see a rhino with its horn still attached to it. but this team believes that it is a price worth paying to save the species. >> the good news for the rhinos is that that horn will grow back. that's the overnight news for this wednesday. for some of you the news continues. for others check back with us a for others check back with us a little later for the "morning captioning funded by cbs it's wednesday, may 18th, 2016. this is the "cbs morning news." hillary clinton calls it a win in kentucky, while bernie sanders picks up oregon. the delegates continue to pile up for clinton, but sanders says he's staying in the race. facing calls for his resignation, tsa's top administrator apologizes to hundreds of passengers who missed their flights out of o'hare this weekend. what went wrong?
